What This Code Means
H10.232 is the ICD-10-CM diagnosis code for serous conjunctivitis, except viral, left eye. This is an inflammation of the clear membrane covering the white part of the left eye that produces a watery discharge, but is not caused by a virus. The condition causes redness, irritation, and excessive tearing without the thick discharge typical of bacterial infections. H10.232 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of conjunctiva (h10-h11).
H10.232 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Verify the laterality is documented as left eye only; if bilateral, use separate codes for each eye (H10.231 for right, H10.232 for left).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H10.232 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
